İstanbul is the most prominent Turkish city in terms of the gradually worsening noise problems associated with the rapid increase in population. This study aims to investigate the noise exposure in the settlements around the link roads connecting the Bosporus Bridge to the European side of the city by the aid of simulations and noise mapping, in the frame of action planning studies performed in İstanbul. Noise maps were generated for Lden and Ln noise indicators with the help of a noise mapping software. Since a considerable part of the settlements is exposed to high noise levels, a noise barrier alongside the link road was proposed as a control measure by the aid of the acoustic simulation. Simulations with the noise barriers suggest that for the Lden time interval the noise affected area over 55 dBA would reduce by 10%, the number of dwellings by 26% and the number of inhabitants by 25%, whereas for the Ln time interval the noise affected area over 45 dBA would reduce by 5%, the number of dwellings by 20% and the number of inhabitants by 20%.

伊斯坦布尔的模拟研究评估隔音屏障前后的噪音暴露

伊斯坦布尔是土耳其最著名的城市,与人口的快速增长相关的噪音问题正在逐步恶化。这项研究的目的是在伊斯坦布尔进行的行动计划研究框架内,通过模拟和噪声映射,研究连接博斯普鲁斯海峡大桥与城市欧洲一侧的连接道路周围居民点的噪声暴露。借助噪声映射软件为L den和L n噪声指标生成了噪声图。由于大部分居民区都暴露于高噪声水平,因此在声学模拟的帮助下,建议在连接道路旁设置隔音屏障作为控制措施。对噪声屏障的仿真表明,对于L den在55 dBA的时间间隔内,噪声影响面积将减少10%,住宅数量将减少26%,居民数量将减少25%,而在L n时间间隔内,在45 dBA的范围内噪声影响面积将减少5%。 ,住房数量增加20%,居民数量增加20%。
